Open access, reuse and maximization of public sector data will enhance participation, transparency and public scrutiny and promote entrepreneurship as well as ensure that businesses, especially start-ups and those in the sector of new technologies, will have the necessary raw material to develop value-added services. The strategic focus is on developing actions for the gradual use of data as a fundamental infrastructure and development resource. The start is given by high-value data or Public Purpose Data, then follows the data in selected thematic areas (eg economy and business) and ends with the effective use of public, business, scientific and personal data on a massive scale. The integrated approach and facilitation of scaling is based on data life cycles per thematic area (eg health, mobility, culture, environment).
